Hearing and vision impairment and social isolation over 8 years in community-dwelling older adults.

BACKGROUND: Little is known about the long-term impact of hearing and vision impairment on social isolation. This study quantifies the association between hearing, vision, and concurrent hearing and vision impairment (dual sensory impairment) and social isolation over 8 years among older adults. METHODS: Data were from the National Health and Aging Trends Study (NHATS), a cohort study (2011 - 2019) of U.S. Medicare beneficiaries aged 65 years and older. Social isolation was measured by a binary indicator incorporating four domains: living arrangement, core discussion network size, religious attendance, and social participation. Hearing, vision, and dual sensory impairments were measured by self-report and modeled categorically (no impairment [ref.], hearing impairment only, vision impairment only, dual sensory impairment). Associations between sensory impairments and odds of social isolation over 8 years were assessed using multivariate generalized logistic mixed models and adjusted for demographic and health characteristics. RESULTS: Among 5,552 participants, 18.9% self-reported hearing impairment, 4.8% self-reported vision impairment, and 2.3% self-reported dual sensory impairment. Over 8 years, hearing impairment only was associated with 28% greater odds of social isolation. Participants with hearing impairment only were more likely to live alone and have limited social participation. CONCLUSION: Greater clinical awareness of hearing impairment as a risk factor for social isolation can increase opportunities to identify and aid older adults who may benefit from resources and interventions to increase social connection and mitigate social isolation.

Hearing loss and cognition: A protocol for ensuring speech understanding before neurocognitive assessment.

INTRODUCTION: Many neurocognitive evaluations involve auditory stimuli, yet there are no standard testing guidelines for individuals with hearing loss. The ensuring speech understanding (ESU) test was developed to confirm speech understanding and determine whether hearing accommodations are necessary for neurocognitive testing. METHODS: Hearing was assessed using audiometry. The probability of ESU test failure by hearing status was estimated in 2679 participants (mean age: 81.4 ± 4.6 years) using multivariate logistic regression. RESULTS: Only 2.2% (N = 58) of participants failed the ESU test. The probability of failure increased with hearing loss severity; similar results were observed for those with and without mild cognitive impairment or dementia. DISCUSSION: The ESU test is appropriate for individuals who have variable degrees of hearing loss and cognitive function. This test can be used prior to neurocognitive testing to help reduce the risk of hearing loss and compromised auditory access to speech stimuli causing poorer performance on neurocognitive evaluation.

Population prevalence of dual sensory loss in community-dwelling US adults 71 years and older: Evidence from the National Health and Aging Trends Study.

BACKGROUND: Existing estimates for the prevalence of dual sensory loss (vision and hearing) among older adults are either based on self-reported measures or aggregated for older age groups. Current and detailed estimates based on objective measures are needed for public health, clinical, and policy decision-making. METHODS: We estimated the prevalence of dual sensory loss (DSL) using National Health Aging Trends Study (NHATS) Round 11 data (2021). We restricted to community-dwelling adults aged ≥71 years with complete sensory testing data (N = 2579). Hearing loss was defined by a 4-frequency (0.5, 1, 2 and 4 kHz) pure tone average for the better-hearing ear (>25 decibel hearing level). Vision loss was defined by the presence of distance, near (logarithm of the minimum angle of resolution >0.30), or contrast sensitivity loss (log contrast sensitivity <1.55). Participants were categorized into three groups: no sensory loss, single sensory loss (vision or hearing loss), and DSL (hearing and vision). Sensory loss prevalence was estimated by age group and sociodemographic characteristics. RESULTS: In weighted analyses, among older Medicare beneficiaries (53% female, 7% Black, 6% Hispanic), 28% had no sensory loss and 22% had DSL. Prevalence of DSL increased with age. Most adults aged ≥90 years experienced DSL (59%), as opposed to single (39%) or no sensory loss (2%). DSL prevalence was greater among older adults with low education attainment (34%) and household income (43%). A higher proportion of older adults with a college education (17%), or from wealthier households (16%), had no sensory loss. CONCLUSIONS: One in 5 community-dwelling Medicare beneficiaries aged ≥71 years have DSL, increasing to 3 in 5 for those aged ≥90 years. Prevalence is higher among older adults with low education attainment and from low-income households, characteristics associated with low treatment. Policies increasing access and affordability of vision and hearing care could benefit millions of older Americans experiencing sensory loss.

Hearing Loss, Hearing Aids, and Satisfaction With Health Care in the National Health Interview Survey.

OBJECTIVE: Hearing loss may negatively impact satisfaction with health care via patient-provider communication barriers and may be amenable to hearing care treatment. STUDY DESIGN: Cross-sectional. SETTING: National Health Interview Survey, a nationally representative survey of noninstitutionalized US residents, 2013 to 2018 pooled cycles. METHODS: Participants described satisfaction with health care in the past year, categorized as optimal (very satisfied) versus suboptimal (satisfied, dissatisfied, very dissatisfied) satisfaction. Self-report hearing without hearing aids (excellent, good, a little trouble, moderate trouble, a lot of trouble) and hearing aid use (yes, no) were collected. Weighted Poisson regression models adjusted for sociodemographic and health covariates were used to estimate prevalence rate ratios (PRRs) of satisfaction with care by hearing loss and hearing aid use. RESULTS: Among 137,216 participants (mean age 50.9 years, 56% female, 12% black), representing 77.2 million Americans in the weighted model, 19% reported trouble hearing. Those with good (PRR = 1.20, 95% confidence interval [CI]: 1.18-1.23), a little trouble (PRR = 1.27, 95% CI, 1.23-1.31), moderate trouble (PRR = 1.29, 95% CI, 1.24-1.35), and a lot of trouble hearing (PRR = 1.26, 95% CI, 1.18-1.33) had a higher prevalence rate of suboptimal satisfaction with care relative to those with excellent hearing. Among all participants with trouble hearing, hearing aid users had a 17% decrease in the prevalence rate of suboptimal satisfaction with care (PRR = 0.83, 95% CI, 0.78-0.88) compared to nonusers. CONCLUSION: Hearing loss decreases patient satisfaction with health care, which is tied to Medicare hospital reimbursement models. Hearing aid use may improve patient-provider communication and patient satisfaction, although prospective studies are warranted to truly establish their protective effect.

Prevalence of Hearing Loss and Hearing Aid Use Among US Medicare Beneficiaries Aged 71 Years and Older.

Importance: National prevalence estimates are needed to guide and benchmark initiatives to address hearing loss. However, current estimates are not based on samples that include representation of the oldest old US individuals (ie, aged ≥80 years), who are most at-risk of having hearing loss. Objective: To estimate the prevalence of hearing loss and hearing aid use by age and demographic covariates in a large, nationally representative sample of adults aged 71 years and older. Design, Setting, and Participants: In this cohort study, prevalence estimates of hearing loss by age, gender, race and ethnicity, education, and income were computed using data from the 2021 National Health Aging and Trends Study. Survey weights were applied to produce nationally representative estimates to the US older population. Data were collected from June to November 2021 and were analyzed from November to December 2022. Main Outcomes and Measures: Criterion-standard audiometric measures of hearing loss and self-reported hearing aid use. Results: In this nationally representative sample of 2803 participants (weighted estimate, 33.1 million individuals) aged 71 years or older, 38.3% (95% CI, 35.5%-41.1%) were aged 71 to 74 years, 36.0% (95% CI, 33.1%-38.8%) were aged 75 to 79 years, 13.8% (95% CI, 12.6%-14.9%) were aged 80 to 84 years, 7.9% (95% CI, 7.2%-8.6%) were aged 85 to 89 years, and 4.0% (95% CI, 3.5%-4.6%) were aged 90 years or older; 53.5% (95% CI, 50.9%-56.1%) were female and 46.5% (95% CI, 43.9%-49.1%) were male; and 7.5% (95% CI, 6.2%-8.7%) were Black, 6.5% (95% CI, 4.4%-8.7%) were Hispanic, and 82.7% (95% CI, 79.7%-85.6%) were White. An estimated 65.3% of adults 71 years and older (weighted estimate, 21.5 million individuals) had at least some degree of hearing loss (mild, 37.0% [95% CI, 34.7%-39.4%]; moderate, 24.1% [95% CI, 21.9%-26.4%]; and severe, 4.2% [95% CI, 3.3%-5.3%]). The prevalence was higher among White, male, lower-income, and lower education attainment subpopulations and increased with age, such that 96.2% (95% CI, 93.9%-98.6%) of adults aged 90 years and older had hearing loss. Among those with hearing loss, only 29.2% (weighted estimate, 6.4 million individuals) used hearing aids, with lower estimates among Black and Hispanic individuals and low-income individuals. Conclusions and Relevance: These findings suggest that bilateral hearing loss is nearly ubiquitous among older US individuals, prevalence and severity increase with age, and hearing aid use is low. Deeper consideration of discrete severity measures of hearing loss in this population, rather than binary hearing loss terminology, is warranted.

Measurement differences in the assessment of functional limitations for cognitive impairment classification across geographic locations.

INTRODUCTION: The measurement of dementia in cross-national contexts relies on the assessment of functional limitations. We aimed to evaluate the performance of survey items on functional limitations across culturally diverse geographic settings. METHODS: We used data from the Harmonized Cognitive Assessment Protocol Surveys (HCAP) in five countries (total N = 11,250) to quantify associations between items on functional limitations and cognitive impairment. RESULTS: Many items performed better in the United States and England compared to South Africa, India, and Mexico. Items on the Community Screening Instrument for Dementia (CSID) had the least variability across countries (SD = 0.73 vs. 0.92 [Blessed] and 0.98 [Jorm IQCODE]), but also the weakest associations with cognitive impairment (median odds ratio [OR] = 2.23 vs. 3.01 [Blessed] and 2.75 [Jorm IQCODE]). DISCUSSION: Differences in cultural norms for reporting functional limitations likely influences performance of items on functional limitations and may affect the interpretation of results from substantive studies. HIGHLIGHTS: There was substantial cross-country variation in item performance. Items from the Community Screening Instrument for Dementia (CSID) had less cross-country variability but lower performance. There was more variability in performance of instrumental activities of daily living (IADL) compared to activities of daily living (ADL) items. Variability in cultural expectations of older adults should be taken into account. Results highlight the need for novel approaches to assessing functional limitations.

Hearing impairment, family financial support, and depressive symptoms among Chinese middle-aged and older adults.

AIMS: Hearing impairment (HI) is prevalent among middle-aged and older adults, but few studies have examined its mental health consequences in China. This study investigated the association of HI with depressive symptoms and whether family financial support moderated the association among adults aged 45 in China. METHODS: Data were obtained from three waves of the China Health and Retirement Longitudinal Study (2011, 2013 and 2015). Hearing impairment was defined as a self-reported hearing problem in one or both ears. Depressive symptoms were measured with CESD-10. Associations between HI and depressive symptoms were modeled using fixed-effect models. RESULTS: People with self-reported hearing loss were more likely than those without hearing loss to have depressive symptoms, with an odds ratio of 1.25 [1.07-1.47]. The association remained significant after adjusting for socio-demographic characteristics, lifestyle behaviors, and health conditions. Family financial support moderated this association. Among those with HI, adults with a higher level of family financial support tend to have better performance on symptoms of depression. CONCLUSIONS: HI was positively associated with depressive symptoms among adults aged ≥45 in China, and family financial support played a buffering role in the relationship between HI and depressive symptoms.

Differences in the measurement of cognition for the assessment of dementia across geographic contexts: Recommendations for cross-national research.

INTRODUCTION: Most cognitive assessments have been developed in high-income countries but are used in diverse contexts. Differences in culture and context may affect the performance of cognitive items. METHODS: We used the Harmonized Cognitive Assessment Protocol (HCAP) surveys in the United States, Mexico, India, England, and South Africa (combined N = 11,364) to quantify associations across countries between cognitive items and cognitive impairment status using age- and sex-adjusted logistic regression. RESULTS: Associations were stronger in the United States (median odds ratio [OR] across items = 0.17) and England (median OR = 0.19), compared to South Africa (median OR = 0.23), India (median OR = 0.29), and Mexico (median OR = 0.28). Items assessing memory (e.g., delayed recall tasks) had the most consistent associations of the largest magnitudes across contexts. DISCUSSION: Transporting cognitive items among countries and cultures warrants caution. Our results can guide the design of future instruments by identifying items that performed well either in individual contexts or across the range of contexts considered. HIGHLIGHTS: Little quantitative evidence exists to guide the design of cognitive assessments in cross-national studies. The performance of cognitive items for the measurement of dementia varied across countries. Items with lower variation across countries (e.g., delayed word recall) should be used in future cross-national assessments. Across countries, there was variability in the performance of language assessments, with the exception of the animal naming task. Results can be used to design future cross-national or location-specific cognitive assessments.

Assessment of hearing and vision impairment in cohort studies collecting cognitive data in older adults.

INTRODUCTION: There are no standard practices for considering sensory impairment in studies measuring cognitive function among older adults. Exclusion of participants with impairments may inaccurately estimate the prevalence of cognitive impairment and dementia. METHODS: We surveyed prospective cohort studies measuring cognitive function in older adults, determined the proportion that excluded participants based on sensory impairment and the proportion that assessed each type of sensory impairment, and described the methods of sensory assessment. RESULTS: Investigators/staff from 85 (of 192 cohorts) responded; 6 (7%) excluded participants with severe impairment; 80 (94%) measured hearing and/or vision impairment, while 5 (6%) measured neither. Thirty-two (38%) cohorts assessed hearing objectively and 45 (53%) assessed vision objectively. DISCUSSION: Findings indicate variation in methods used to assess sensory impairment, with potential implications for resource allocation. To ensure equitable inclusion of study participants, consensus is needed on best practices standardized protocols for assessment and accommodations of sensory impairment.

Self-reported dual sensory impairment, dementia, and functional limitations in Medicare beneficiaries.

BACKGROUND: Vision and hearing impairments often co-exist with dementia, and all are independently associated with limitations in daily activities. Our aim was to examine the association of dual sensory impairment with functional limitations, and further examine the combined estimated association of sensory impairment and dementia with these functional limitations. METHODS: Cross-sectional analysis of the National Health and Aging Trends Study (NHATS), a population-based cohort of Medicare beneficiaries, was performed. Participants were selected from the 2015 round. Survey weighted Poisson regression models adjusted for dementia, demographics, and health status variables examined the association of self-reported dual sensory impairment (no sensory impairment, single sensory impairment, dual sensory impairment) with scores of limitations in mobility, self-care, and household activities. Models were repeated to take into account the combined effects of dual sensory impairment and dementia. RESULTS: Overall, 7124 participants representative of Medicare beneficiaries 65 years or older were included. Of them, 43.9% were 75 years or older and 55.3% were female. Older adults with dual sensory impairment had greater limitations with mobility (prevalence rate ratio [PRR] = 1.45, 95% CI = 1.28-1.63), self-care (PRR = 1.41, 95% CI = 1.25-1.59), and household activities (PRR = 1.54, 95% CI = 1.37-1.72) compared with those without sensory impairment. They also had greater limitations than those with a single sensory impairment across the different activity categories. In models taking into account the combined estimated effect of both sensory impairment and dementia, those with dual sensory impairment and dementia had greater limitations than those without sensory impairment or dementia in each category (mobility: PRR = 1.85, 95% CI = 1.59-2.14, self-care: PRR = 1.86, 95% CI = 1.59-2.18, household: PRR = 2.41, 95% CI = 2.09-2.77). CONCLUSIONS: Older adults with dual sensory impairment had greater functional limitations compared with those without sensory impairment and those with a single sensory impairment. Strategies to improve visual and/or hearing function (e.g., sensory aids, rehabilitation) could potentially help prevent or minimize disability, even among those with dementia.

Prevalence of Concurrent Functional Vision and Hearing Impairment and Association With Dementia in Community-Dwelling Medicare Beneficiaries.

Importance: Impairments in vision or hearing are common and have been independently linked to higher risk of dementia in older adults. There is a limited understanding of the prevalence of concurrent functional vision and hearing impairment (dual sensory impairment) and its contribution to dementia risk. Objective: To examine the age-specific prevalence of functional dual sensory impairment among older adults, and to investigate the cross-sectional and 7-year longitudinal associations between functional dual sensory impairment and dementia. Design, Setting, and Participants: This cohort study of 7562 older adults used data from the US National Health and Aging Trends Study (NHATS), a nationally representative cohort study of community-dwelling, Medicare beneficiaries aged 65 years and older in the US. Participants in the study with complete data on hearing, vision, and dementia were included in analysis. Data were collected between 2011 and 2018, and between March 2018 and May 2020. Exposures: Self-reported functional sensory impairments (ie, no sensory impairment, functional vision impairment only, functional hearing impairment only, and functional dual sensory impairment). Main Outcomes and Measures: Age-specific prevalence of functional sensory impairments was calculated. Generalized linear regression with a complementary log-log link and a discrete time proportional hazards model with a complementary log-log link were used to assess the cross-sectional and 7-year longitudinal hazard of dementia. Results: Of 7562 participants, 3073 (40.7%) were ages 80 years or older and 4411 (58.3%) were women. Overall, 5.4% (95% CI, 4.7%-6.1%) of participants reported functional vision impairment only, 18.9% (95% CI, 18.9%-17.8%) reported functional hearing impairment only, and 3.1% (95% CI, 2.7%-3.5%) reported functional dual sensory impairment (prevalence estimates are weighted). Participants reporting sensory impairments were older (no impairment: age ≥90 years, 2.12% [95% CI, 1.79%-2.46%] vs functional dual sensory impairment: age ≥90 years, 20.06% [95% CI, 16.02%-24.10%]), had lower education (no impairment:

Assessment of Sensory Impairment and Health Care Satisfaction Among Medicare Beneficiaries.

Importance: Satisfaction with care is associated with improved quality of care and health outcomes. Sensory impairment can be a barrier to effective communication and access to care, and this may result in reduced satisfaction with care. Objective: This study examined the association between sensory impairment and health care satisfaction among Medicare beneficiaries. Design, Setting, and Participants: This cross-sectional study used data from the 2017 Medicare Current Beneficiary Survey (MCBS), a nationally representative in-person survey of Medicare beneficiaries. Functional sensory impairment was categorized as no sensory impairment, hearing impairment, vision impairment, and dual sensory impairment. Patient dissatisfaction included responses on quality of care, ease to get to a doctor, out-of-pocket costs paid, information given, and doctors' concern with overall health rather than an isolated symptom or disease. Exposures: Self-reported functional sensory impairment. Main Outcomes and Measures: Multivariable-adjusted odds ratios (ORs) of the association between dissatisfaction with care and sensory impairment. Results: A total of 10 783 respondents representing 44 736 889 Medicare beneficiaries (8944 [85.3%] aged ≥65 years, 5733 [52.9%] women, and 8195 [75.5%] non-Hispanic White) were included. Dual sensory impairment compared with no sensory impairment was associated with the highest odds of dissatisfaction across outcomes, including quality of care (OR, 1.52; 95% CI, 1.12-2.08). Compared with no sensory impairment, having dual sensory impairment (OR, 1.82; 95% CI, 1.40-2.37), hearing impairment (OR, 1.67; 95% CI, 1.29-2.17), or vision impairment (OR, 1.56; 95% CI, 1.18-2.08) were associated with dissatisfaction with the information provided about what was wrong. Those with hearing impairment (OR, 1.38; 95% CI, 1.03-1.86) or dual sensory impairment (OR, 2.03; 95% CI, 1.55-2.66) were more likely to be dissatisfied with doctors' concern with overall health compared with those with no sensory impairment. Having dual sensory impairment or vision impairment only was associated with greater odds of dissatisfaction with ease to get to a doctor (dual sensory: OR, 1.69; 95% CI, 1.24-2.30; vision: OR, 1.63; 95% CI, 1.14-2.31) and out-of-pocket costs paid (dual sensory: OR, 1.27; 95% CI, 1.04-1.54; vision: OR, 1.31; 95% CI, 1.07-1.61). Conclusions and Relevance: These findings contribute to the growing body of literature on sensory impairment and patient satisfaction and have implications for health care system planning and spending to provide patient-centered care for older adults.

Accompaniment to healthcare visits: the impact of sensory impairment.

BACKGROUND: Millions of older adults in the United States experience hearing, vision, and dual sensory impairment (concurring hearing and vision impairment) yet little research exists on their needs in interactions with the healthcare system. This piece aims to determine the use of accompaniment in healthcare interactions by persons with sensory impairment. METHODS: These cross-sectional analyses included data from the 2015 Medicare Current Beneficiaries Survey and survey weighting provided by Centers for Medicare and Medicaid Services. Adjusted odds of reporting accompaniment to healthcare visits and given reasons for accompaniment among United States Medicare beneficiaries with self-reported sensory impairment (hearing, vision, and dual sensory impairment) were examined. RESULTS: After excluding observations with missing data, 10,748 Medicare beneficiaries remained representing a 46 million total weighted nationally representative sample, of which 88.9% reported no sensory impairment, 5.52% reported hearing impairment, 3.56% reported vision impairment, and 0.93% reported dual sensory impairment. Those with vision impairment and dual sensory impairment had 2.139 (95% confidence interval [CI] =1.605-2.850) and 2.703 (CI = 1.549-4.718) times the odds of reporting accompaniment to healthcare visits relative to those without sensory impairment. A secondary analysis suggests communication needs as the primary reason for accompaniment among persons with hearing loss, while those with vision impairment were more likely to indicate transportation needs. CONCLUSIONS: Healthcare accompaniment is common for persons with sensory loss and healthcare systems should consider accommodations for and leveraging accompaniment to improve healthcare for persons with sensory impairments. In light of the current COVID-19 pandemic, as hospitals limit visitors to reduce the spread of infection, arrangements should be made to ensure that the communication and transportation needs of those with sensory impairment are not neglected.

Trends in Health Care Costs and Utilization Associated With Untreated Hearing Loss Over 10 Years.

Importance: Nearly 38 million individuals in the United States have untreated hearing loss, which is associated with cognitive and functional decline. National initiatives to address hearing loss are currently under way. Objective: To determine whether untreated hearing loss is associated with increased health care cost and utilization on the basis of data from a claims database. Design, Setting, and Participants: Retrospective, propensity-matched cohort study of persons with and without untreated hearing loss based on claims for health services rendered between January 1, 1999, and December 31, 2016, from a large health insurance database. There were 154 414, 44 852, and 4728 participants at the 2-, 5-, and 10-year follow-up periods, respectively. The study was conceptualized and data were analyzed between September 2016 and November 2017. Exposures: Untreated hearing loss (ie, hearing loss that has not been treated with hearing devices) was identified via claims measures. Main Outcomes and Measures: Medical costs, inpatient hospitalizations, total days hospitalized, 30-day hospital readmission, emergency department visits, and days with at least 1 outpatient visit. Results: Among 4728 matched adults (mean age at baseline, 61 years; 2280 women and 2448 men), untreated hearing loss was associated with $22 434 (95% CI, $18 219-$26 648) or 46% higher total health care costs over a 10-year period compared with costs for those without hearing loss. Persons with untreated hearing loss experienced more inpatient stays (incidence rate ratio, 1.47; 95% CI, 1.29-1.68) and were at greater risk for 30-day hospital readmission (relative risk, 1.44; 95% CI, 1.14-1.81) at 10 years postindex. Similar trends were observed at 2- and 5-year time points across measures. Conclusions and Relevance: Older adults with untreated hearing loss experience higher health care costs and utilization patterns compared with adults without hearing loss. To further define this association, additional research on mediators, such as treatment adherence, and mitigation strategies is needed.

The Health of America's Aging Prison Population.

Older incarcerated individuals comprise the fastest growing demographic in the US prison system. Unhealthy lifestyles among incarcerated individuals and inadequate health care lead to earlier onset and more rapid progression of many chronic conditions that are prevalent among community-living older adults. There are limited peer-reviewed epidemiologic data in this area; however, there is growing interest in identifying strategies for housing aging incarcerated individuals, delivering appropriate health care in prisons, and coordinating after-release health care. In this systematic review, we summarize the epidemiologic evidence of the health challenges facing the aging US prison population. Our comprehensive literature search focused on health outcomes, including diseases, comorbid conditions, mental health, cognition, and mobility. From 12,486 articles identified from the literature search, we reviewed 21 studies published between 2007 and 2017. All the studies were observational and cross-sectional, and most (n = 17) were based on regional samples. Sample sizes varied widely, ranging from 25 to 14,499 incarcerated people (median, 258). In general, compared with their younger counterparts, older incarcerated individuals reported high rates of diabetes mellitus, cardiovascular conditions, and liver disease. Mental health problems were common, especially anxiety, fear of desire for death or suicide, and depression. Activities of daily living were challenging for up to one-fifth of the population. We found no empirical data on cognition among older incarcerated individuals. The findings of this review reveal few empirical data in this area and highlight the need for new data to drive policy and practice patterns that address critical health issues related to the aging prison population.
